More Information
Summary:A combination solenoid operated flow control valve and solenoid operated by-pass valve and pressure transducer are disposed in a common housing with a common electrical receptacle for connection thereto. The pressure transducer senses differential pressure across a metering orifice. The pressure transducer measures flow through the metering orifice during leak testing. A vacuum is drawn in the system for leak testing. The by-pass valve is opened to bypass the metering orifice and permit full flow to the flow control valve during normal engine operation.
